When the backdoor pilot for Feds played on The Rookie, my original intention was to give the show no attention, if it was picked up. However, as they started casting, I saw a number of actors that I enjoyed, so I gave it a try.
Now I find myself enjoy watching the secondary characters and aggressively hate watching the lead. Don't get me wrong, Niecy Nash is fine in the right environment. She is great on something like Reno 911 where she is in an ensemble and where the whole concept is goofy. But her obnoxious portrayal of an obnoxious character is so irritating, it makes it nearly impossibly to watch.
The Simone Clark character walks in, specifically into a group that was harnessed with her against their will in the backdoor pilot, and is basically the Messiah of the FBI, telling everyone exactly how to do their jobs, while also comporting herself any way she pleases.
I find myself still watching for the other characters and storylines I find more interesting, as well as for the interaction between the parent series and the spinoff characters, but every time she is focus, I'm completely pulled out of the moment. This is one of those times that a shock move like removing the main character would be a huge boost to a decent show.
